Efficiency of lattice-based security mechanisms supporting public tasks on digital integration platforms

Integration platforms are the solution increasingly used by the public administration in Poland in order to make public tasks available and implement the tasks on these platforms (in the form of electronic services). In earlier publications, the author proposed a mathematical model based on lattice mechanisms that ensures the secure provision of these services (from a confidentiality perspective). In the following publication the author's model was cited (its main elements) and then the analysis of a time efficiency of the approach with using lattice mechanisms with the general model was performed. The efficiency examined concerned both the implementation of public tasks – and more precisely the verification of their correctness from the security perspective before the implementation as well as concerned an expansion of the process of handling the public task. The author has demonstrated that in both cases it is appropriate to use the lattice solution, as its time efficiency is better.
